Digital delay trigger

Abstract

The invention provides a digital delay trigger, comprising: a reference clock module, an interaction platform, a DPDT (double pole double throw) module, an output module and a power supply, wherein the DPDT module generates a frequency control word, a first delay control word and a second delay control word according to the frequencies and delays of each channel set by a user through the interaction platform, and generates a first pulse output signal according to the first delay control word, the frequency control word and a reference clock generated by the reference clock module; the output module outputs a second pulse output signal according to the first pulse output signal and the second delay control word. By integrating all the functional modules, the pulses with multiple paths, wide rang, low jitter, independent and adjustable delay and frequency of each path can be output, and high-precision adjustment of multi-path pulse delay is realized. Therefore, the entire system is highly integrated, cost and complexity are reduced, and reliability is improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment manufacturing, in particular to a single-chip high-precision digital delay trigger. Background technique [0002] Ultrashort pulse mode-locked laser systems are usually composed of femtosecond oscillators, regenerative amplifiers, stretching and compressors, multi-pass amplifiers and other subsystems. Synchronization, and the switching time of the Pockels cell and the triggering time of the pump light of the multi-pass amplifier also need precise synchronization and delay adjustment based on the above timing sequence to ensure stable and reliable operation of pulse amplification to provide high quality and high stability amplified laser pulses. [0003] For the synchronization technical requirements of optical systems, traditional general-purpose instruments and delay technologies applied to communication systems (such as counter delays, phase-locked loop delays, and transmission lin...
